First my WFCO story: I had a battery on my fiver destroyed last summer. I was also using one to charge the batteries on my ham radio repeater. I ruined one of those too. I now have Boondockers and no issues.
I am also looking for a 3000W.
The Predator doesn't interest me if I can't get parts to repair it. It doesn't matter if I can buy three for the price of one Honda or not. I don't like throwing stuff away.
The Champions are popular because they are inexpensive but they are noisy. The Honda is 49dB at 1/4 load while the Champion is 59dB at 1/4 load. This means it's twice as loud. The Honda at full load is the same loudness as the Champion at 1/4 load. If you can put the genny 50' from your RV it's no big deal. For me it will be mounted on my RV and therefore needs to be as quiet as possible.
My plans are getting the Honda EU3000, adding a remote control as well as choke kit. I also camp in the mountains and it does get hot sometimes.Last year around Durango/Silverton it was mid 80's and at that elevation the sun is hot. I will try the MicroAir Easy Start first and if necessary have high altitude jets.
My plan isn't cheap by any means but the Honda should last for years and parts are readily available.
